A user equipment (UE) may increase the reliability of transmission of a Physical Uplink Control Channel (PUCCH) by transmitting repeated copies of the PUCCH, according to a repetition pattern spanning one or more slots. In an intra-slot mode, more than one copy may be transmitted within each configured slot, with or without frequency hopping. The number of copies as well as a temporal gap between the transmission of successive copies may be configured by the network. The repetition pattern may or may not be interrupted by slot boundaries. In an inter-slot mode, one copy is transmitted per configured slot. Different copies may be transmitted in different directions, according to a spatial consistency pattern. The UE may perform repeated transmission of PUCCHs to different Transmission-Reception Points (TRPs) using respectively different timing advances and/or transmit power levels.
Legal claims defining the scope of protection, as filed with the USPTO.
2. The method of claim 1, wherein two or more of the repetitions occur in a first of the one or more slots.
3. The method of claim 2, wherein the one or more slots comprise a plurality of slots, wherein a time between successive repetitions of the N repetitions is constant and not interrupted at slot boundaries.
4. The method of claim 2, wherein the one or more slots comprise a plurality of slots, wherein a time between successive repetitions of the N repetitions is constant within each of the slots, wherein none of the N repetitions straddles a slot boundary.
5. The method of claim 2, wherein a mode of transmitting the N repetitions is determined by a Radio Resource Control (RRC) configuration message received from a network, wherein the RRC configuration message also indicates a time offset between successive repetitions of the N repetitions.
13. The method of claim 12, wherein the first set of transmission parameters includes a first timing advance and/or a first transmission power, wherein the second set of transmission parameters includes a second timing advance and/or a second transmission power.
14. The method of claim 1, wherein said transmitting the N repetitions of the first PUCCH is performed according to an inter-slot repetition mode and a short PUCCH format.
